Re: exhaust
Now if you have a conventional carb and a vacuum dizzy, it's all good...

Re: exhaust
No, he wont. Running open shorties wont burn a valve. As posted above, this is an old wives tale. I wouldnt recommend running an open port though(no header at all). Thats a real bad idea for a whole bunch of reasons. Though it is a rather awe inspiring event to see in the dark.

Re: exhaust
It will not hurt your engine. I drove around a 96 monte carlo for 2 weeks. It was the worst 2 weeks of my life. It was a stock V6, it made so much noise, I don't know why you would want to do that, its an invitation to getting pulled over or possibly a ticket

Re: exhaust
well i have the headers on but my y-pipe didnt line up with it so i have to cut the y-pipe near the cat. so now i just have the headers hooked up. so it wont do anything even if i have a o2 sensor??? i just dont want any problems with the motor lol i just droped it in and i dont even want to go threw that trouble again lol.

Re: exhaust
You have now heard the truth. It's false.
See above.
Running with completely open exhaust ports is a different story. I have run engines on the test stand with headers and without headers (open ports).
Running with open ports (no manifold or header) will make the engine run lean, which will damage exhaust valves (over time).
I've had to adjust previously dialed-in carbs, richer when put on an engine with open ports, then adjust them back when open headers were put on. With open headers or even iron manifolds, no adjustment is needed.
While we're slaying old wives tales, you know you have to put a battery on a block of wood if you put it on concrete, to keep the concrete from sucking the juice out of it, right?
Old wive's tale.
People put batteries on wood blocks so they don't end up with a permanent white rectangle on their concrete from the battery acid. Some idiot saw that and someone like me said: "you have to do that to keep the battery from running down"... and then laughed like hell as soon as he left.

Re: exhaust
ohhhh..... Huh, well that explains all my white rectangles on my garage floor... Damn.
Yea, I had to run my car with open heads for the break in, then to drive it across town to get the exhaust made up to match my headers. Get a lot of looks doing that... Driving around with big oil-rig style head phones on......
It's DEAFENING. It won't hurt anything though. I blackened my oil pan due to my collector style, but the soot just wiped off. Probably had pretty hot oil for that time...
